New Advances in Green Extraction Technology for Natural Products

Dear Colleagues,

Green and sustainable extraction techniques are being intensively developed nowadays to replace or reduce the conventional, environmentally unfriendly, solvent-based techniques. The development of these novel techniques, such as microwave-assisted extraction, ultrasound-assisted extraction, pressure-assisted liquid extraction, supercritical CO₂ extraction, pulsed electric field assisted extraction, and enzyme-assisted extraction, etc., helps to minimise the negative impact on the environment and human health by reducing or eliminating the use of extraction solvent, as well as by reducing extraction time and energy consumption. Some of the major industries, such as the food, pharmaceutical, cosmetic and agricultural industries, are increasingly using extracts from natural products and/or their specific metabolites. At least 50% of the energy consumption in industrial processes is related to the extraction cycle, meaning that the implementation of new and optimization of existing extraction methods are important economic and environmental factors.

In most cases, the application of green extraction techniques leads to an increase in the extraction yield of the target metabolites, as well as differences in the chemical composition of the isolated natural products.

This Special Issue on “New Advances in Green Extraction Technology of Natural Products” will present new research advances in green extraction technologies that lead to improved extraction reproducibility, higher extraction yields, reduced energy, and solvent consumption.

We hope you will consider participating in this Special Issue.

Sincerely,

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
